A 'MEoHAnIcALLY-ornRAr n FA Application filed July 18, 1921. Sean No. 485,453.

Stateof est Virginia, have invented certain new and useful Improvements in Mechanically-Operated Fans, of which the following'is a full and complete specification, reference being had. to the accompanying drawing. 7

The present invention has reference to a portable ventilating fan'and the main objeet is to provide a structure of'this charac ter simple and rugged in construction, and cheap to manufacture.

It is a further object of the present invention to provide a portable mechanically driven ventilating fan of adaptable construction so that the fan may be either placed on a table or pedestal or'suspended from over head. In order to render the'inventi-on. entirely clear apreferred embodiment is illustrated in the accompanying drawings in which Fig. 1 shows'a view of the complete structure;

Fig. 2 shows a cross section of the same,

, and

Fig. 3 shows a suspending means adapted to be used with the structure when the same is used as an over-head fan.

In the form illustrated the fan comprises a box or enclosure 1 constructed of Wood or metal, in which the clock work for operating the fan is enclosed. Mounted upon the top of this enclosure and fitted over or journalled upon a rotating shaft hereinafter described. is a pedestal 2 having an enlarged top 3 in which a pair of bevel gears 1 and 5 are located. By means of these gears motion is transferred from the vertical shaft 6 to the horizontal shaft 7 upon which the fan blades 8 are mounted. If desired, a suitable fan guard may be provided for the fan blades the same being mounted upon .the enlarged head 3, but as the fan guard forms no part of the present invention the same is not shown.

The power for operating the fan through the medium of shaft 6 is obtained from a powerful spiral spring 9. This spring is wound by means of a crank 10 removably fitted on a winding shaft 11 carrying at its inner end a spur gear 12 meshed with a gear 13 which is rigidly fixed to the inner end of the spring. A coil spring 14 closely encircles being free.

the winding shaftll, the inner end of this the driving mechanism and theouter end v When thewinding shaft 11 is rotated by the crank in a clock-wise direction the spring l l tends to loosen and permit shaft 11 to freely rotate and the spring 9 can therefore readily be wound. When *winding'effort is no longer applied to the winding shaft 11, the spring 9 will, ofcourse', tend to rotate shaft 11 in an opposite or counter clock-wise direction. Such rotation, however, serves to tighten spring member 14.- about shaft 11 so that'the same is securely gripped and prevented from rotation.

Thespring member 14, therefore, serves as a .noiseless and efficient ratchet andpawl mechanism. I

Gear wheel 16 is carried by the spring drum and serves to drive the small pinion 17 ,which is fixed to gear 18, the gear 18 in tuna-meshes with pinion-'19 mounted on coil spring 15being fixed to the frame of shaft 20 at the upper end of which is car- 1 ried gears 21 and 22. Gear 21 meshes with pinion 23 mounted upon the lower end of fan operating shaft 6. By means of the large gear reduction existent between the spring drum 9 and the shaft 6 and the further reduction due to bevel gears 1 and 5, the fan 8 will operate for several hours upon one winding of the spring.

Pinion 22 operates shaft 24: through the medium of a gear 25 and pinion 26. disc 25 is carried at the upper end of shaft 24L and has a plurality of holes 26 located at various distances from its center. A. lug 27 is fixed to the pedestal 2 and has pivotally mounted thereon a connecting rod. 28. The outer end of this connecting rod carries a pin 29 which may be inserted in any of the holes 26 or in the stationary hole 30 in the top frame of the enclosing member 1. When the pin 29 is inserted in any of the holes 26, the pedestal is given an oscillating movement, the extent of which depends upon the particular hole in the disc 25 which is selected When the pin 29 is inserted in the stationary hole 30, the fan no longer oscillates but is of the fixed or stationary type.

A gear 31 is fixed to the lower end of shaft 20 and operates to drive a centrifugal governor 32 through the medium of the car 33. The governor weights function to to the governor disc 34 and therefore the speed of the fail'is're'gulated by means of a rod 37 carrying at its outer extremity a milled head 38. head the rod may be screwed to a greater or less extent into post 39 against the longer end of' the bell crank lever 36, Which is resiliently urged against the inner end of rod 37= by means of a leaf spring 40.-

l Vhen it is desired to convert the fan from the ordinary type into the ceiling type, the pedestal 2 with the fan and associated gearing 4: and 5 is removed and a shaft tl is inserted through the top of the enclosing receptacle. This shaft is also inserted through a gear 42 meshing; with an idler gear 43 carried on a shaft 4A and transmitting motion from thegear 21 to the shaft 41'. A fan of the ceilingtype is mounted upon the lower end of shaft 41 and the entire structure is suspended by means of hanger illustrated in Fig. 3, Which has a plurality of-jscrew holes is adapted to co operate With screw holes 46 of the enclosingreceptacle 1.

The windingcrank 10 is removable and may be enclosed ithin a recess provided with the receptacle 1. A- cover for the top of receptacle 1 may also be provided for By turning this milled enclosing the oscillating'structure and having a single opening for the pedestal 2 to project through.

It is obvious that details of construction and arrangement of parts may be varied Without departing from the spirit of the invention as set forth in the appended claims.

What I claim is:

1. In a mechanical fan, in combination With a base including a spring motor and a vertical rotating shaft driven thereby, of a pedestal journalled on said shaft, a cam driven from said spring motor; a link con- 11ecti1'1gs'aid pedestaland cam, a fan shaft journalled in'sa'id pedestal and gearing between tlie said shafts.

2. In a mechanical fan, the combination with a ba's'e including aspi'iifg' motor and a vertical rotating drive shaft actuated thereb'y, a pedestal joarnaied on said shaft, a fan shaft carried by said pedestal and operatedby said verticalshaftiactrm r0 tated'by said spring motor inap'la ne' perpendicular to said ped'estal, a link pivoted to said pedestal and adapted selectively for engagement With said-cam and for anchoring attachment to said base.

In testimony whereof; I hereunto affix my signature.
